6 Claims. (01. 200-168) This invention relates to a casing that is esmaybe riveted to hold the parts together. A pecially useful for housing anelectric switch but binding post 14 is provided on each cross memis notrestricted to this particular use. The casber 13 near one of the sidemembers 12 and the ing is made in separable parts which can be held endsof two wires 15 of an electric circuit are 5 in assembled relation by anut on a screw-threadconnected to the binding posts 14.
